为了更好的理解电池均衡的作用,现有的一些数据是非常有必要的。这里参考了国外已经研究的文档,它们分别为:
A Comparison of Active and Passive Cell Balancing Techniques for SeriesParallel Battery Packs
Active Cell Balancing increases effective battery capacity and reduces capacity variance
Benefits of Cell Balancing in BLUESHAPE Li-Ion battery packs
Cell balancing and cell variations in large capacity Liion cells
A balanced and monitorting system for battery cell stacks in electrical vehicles
SAE_A Battery Electronics Unit (BEU)for Balancing Lithium-Ion Batteries 等
前面已经说了主要是端电压和内阻的区别导致电池之间的不均匀性,初始的可能还好,经过多个cycle之后这些参数的差异性的恶化的症状开始显现。
关于温度差异性,得再继续找数据看看。
